D = {5; 7; 9; 11}
y = 45 - 3x
substitute the values of x from the domain to the equation:

for x = 5: y = 45 - 3 · 5 = 45 - 15 = 30for x = 7: y = 45 - 3 · 7 = 45 - 21 = 24for x = 9: y = 45 - 3 · 9 = 45 - 27 = 18for x = 11: y = 45 - 3 · 11 = 45 - 33 = 12
Answer: The range is { 12; 18; 24; 30}.

ANSWER

EXPLANATION

Given information

The sum of the two numbers is 76

The larger number is 16 more than 2 times the smaller number

Let the two numbers be x and y

x ----> Larger number

y ----> smaller number

To find the value of x and y, follow the steps the below

Step 1: Write the algebraic expressions for the statement given

The sum of the two numbers is 72

Mathematically, this can be expressed as

$\text{ x + y = 72 ----------- equation 1}$

Also, the larger number is 16 more than twice
